▎ 摘　　要

NOVELTY - Graphene-polypyrrole composite heavy-duty anticorrosive paint comprises solidified epoxy resin, graphene-polypyrrole composite material and zinc powder, where the mass ratio of the graphene-polypyrrole composite material and the solidified epoxy resin is (0.3-0.8):100 and the mass ratio of the graphene-polypyrrole composite material and the zinc powder is (0.0075-0.03):4. USE - Used as graphene-polypyrrole composite heavy-duty anticorrosive paint. ADVANTAGE - The paint improves the utilization rate of zinc and the service life of the primer, and overcomes the problems of low zinc utilization of the existing zinc-rich primers, pollution and waste. The method is simple and easy to realize industrialized production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing graphene-polypyrrole composite heavy-duty anticorrosive paint, comprising: (i) mixing the graphene-polypyrrole composite material with a solvent to obtain a suspension; (ii) adding the suspension into the solidified epoxy resin, and uniformly stirring to obtain a mixture; and (iii) adding zinc powder into the mixture and stirring to make it uniformly mixed.
